Ferrari's Kimi Raikkonen was fastest in Formula One testing with all 10 teams in action yesterday and new F1 outfit Brawn GP recording the third quickest lap time.

Raikkonen's best lap time of 1 minute, 20.314 seconds around the Catalunya Circuit was more than half a second faster than his closest rival, Kazuki Nakajima of Williams.

Rubens Barichello was behind the wheel for Brawn GP for the first time since Ross Brawn bought the team from Honda on Friday. The 37-year-old Brazilian had a fastest time of 1:20.966 from 111 laps, with Brawn GP adapting well to its Mercedes engine.

"If the management group, because it is not just myself, had not taken this task on, there would be no team," Brawn told autosport.com of the Honda buyout.

Brawn confirmed that chief executive Nick Fry would stay on with the team, while Barichello said he hadn't spoken to Bruno Senna since being picked over the nephew of the late three-time champion Ayrton Senna to partner Jenson Button this season.

Toro Rosso's second day in the 2009 car went badly after Sebastien Bourdais had a mechanical problem after 14 laps and partner Sebastien Bourdais managed only six laps.
